In particular, phosphorene allotropes present a fertile landscape for the development of high-performance FETs. Using density functional theory-based methods, we have systematically investigated the influence of electrostatic gating on the structures, stabilities, and fundamental electronic properties of pristine and carbon-doped monolayer (bilayer) phosphorene allotropes. The remarkable flexibility of phosphorene allotropes, arising from intra- and interlayer van der Waals interactions, causes a good resilience up to equivalent gate potential of two electrons per unit cell. The resilience depends on the stacking details in such a way that rotated bilayers show considerably higher thermodynamical stability than the unrotated ones, even at a high gate potential. In addition, a semiconductor to metal phase transition is observed in some of the rotated and carbon-doped structures with increased electronic transport relative to graphene in the context of real space Green’s function formalism.1 p.application/pdfengcc-by (c) Malayee, F.M. et al., 2023http://creativecommons.org/licenses/by/3.0/es/TransistorsElectroestàticaEstructura químicaTransistorsElectrostaticsChemical structureinfo:eu-repo/semantics/article7457812025-02-25info:eu-repo/semantics/openAccess
